Cant see the left side if its low then jet mite need a prick if thats not it try turn the flame spreader in diff. spot
some of my stoves gets a streaky yellow bit through it too. Dirty/ not the best kero..Not hot enough. After you even up the flame it should blue out.Better. I think! it gets hotter and vaps the fuel better.Spreader should go cherrie red when it heats up.
This may be of help. Well, it helps me get through an otherwise trying day. to view a bit of Cherry Red occasionally.
